Rosario was among a group of people who partied at the victim's apartment in Philadelphia on Feb. 24, police said.
A witness told investigators that an attacker entered the woman's bedroom and assaulted her at knifepoint. The 30-year-old victim then jumped from her apartment window. She remains in critical condition at a Philadelphia hospital, Darby said.
Rosario is charged with rape, sexual assault, terroristic threats, unlawful restraint and other offenses. He is also charged with attempted rape in an alleged assault on the woman's 23-year-old roommate, police said.
Rosario, who was located with help from New York authorities and the FBI, plans to waive extradition and should be in Philadelphia on Tuesday, police said.
